Coherence

On her way to a dinner party with good friends, Em discovers that her phone has not only lost power, but has literally cracked, the first abnormality on a night that will turn into a mind-bending journey that twists reality over on itself. As unexplained events begin to stack up, the dinner guests realize that they are trapped in an impossible puzzle. Worse, Em begins to suspect that someone from their own house may be in league with an ominous and possibly dangerous house two dark blocks away.
